SPECIFICATION forming part of Letters Patent No. 563,97*?, dated July14, 1896.

Application i'iled May 25,1892. Renewed .Tune 8,1896. Serial No.594,800. (No model.)

T0 @ZZ whom t may concern:

Be it known that I, CLARENCE R. MAcoM- BER, a citizen of the UnitedStates, residing at Vorcester, in the county of Vorcester and State ofMassachusetts, have invented a new and useful Improvement in ChemicalFire- Pails, of which the following is a specification.

The object of this invention is to produce a new and improved fire-pailwhich will direct a chemicalized stream to the seat of the fire, and theespecial object of this invention is to provide a fire-pail which willact automatically.

To these ends the invention consists of the combinations and features ofconstruction as hereinafter described, and more particularly pointed outin the claims at the end of this specification.

In the accompanying drawings, Figure lis asectional elevation of alire-pail constructed after my invention. Fig. 2 is a separate view ofthe fusible link or connection used to hold the pail in one position.Fig. 3 is a side elevation at right angles to Fig. l on a reduced scale,showing the pail as the same normally stands. Fig. 4 is a view similarto Fig. 3, showing the pail in operation.

Referring to the drawings and in detail, A represents a pail of anysuitable construction preferably made of strong sheet metal. The same isdivided transversely by a suitable partition B, and by a verticalpartition C, eX-

tending from the transverse partition B to the -bottom of the pail intotwo compartments 20 and 2l and a mixing-chamber 22.

The partition B has two holes cut therein to form valve-seats connectingwith each of the compartments 2O and 21, and surrounding thesevalve-seats are the guards 23 and 24, in which are mounted the valves Gand G, which may be glass balls, as shown.

Screwing into the top of the pail is a suitable cap H, which has aflange h, and, if desired, under this flange may be placed a rubbergasket g, so that a tight joint may be formed between the cap H and thetop of the pail. The cap Il has formed thereon a hexagonal nut J ,bymeans of which the cap H may be firmly secured to the same. The cap Hhas a small hole I bored through the same, and screwed into this hole lis the nozzle K. A

suitable deflector or sprayer L is mounted as shown, and may beconnected by four small rods Z to the cap H.

The pail is hung by a suitable bail D and the bail is connected to thepail below its center of gravity, and, if desired, the bail'may bepointed at its ends, as at E, to form nice joints with the pail, wherebythe pail may turn easily in the bail, as hereinafter described.

The pail is shown as suspended from a suitable hook F.

The pail is kept normally from turning over by a fusible or combustibleconnection. This connection, as shown, specifically consistsof a smallwire hook M, connected to the top of the deflector L, and a small hook30, which is bent, as shown in Fig. 2, and is twisted around the top ofthe bail, as at 10 10. The hook F is caught on to the bail between theportions l0 l0, whereby the hook 30 will be prevented from sliding ineither direction along the bail` The hooks M and 30 are connected by asuitable fusible link N, which governs the operation of the device.-

The operation of my device is apparent and as follows: The pail isnormally suspended from the ceiling of the room or over any place whereit is desired to protect from fire, as shown in Fig. 3, and as there isa slight give in the connection between the top of the pail and the bailthe pail will swing slightly, as

indicated, so that there will be a slight pull exerted on theconnection. The compartments 2O and 2l are filled with suitablesolutions, preferably one an acid solution and the other an alkalisolution. If now fire should break out orthe pail be` exposed toabnormal temperature, the link N will melt. This will allow the parts toturn over within the bail or to the position shown in Fig. 4.. The twosolutions in the compartments 2O and 2l will now both run into themixing-chamber 22 and willv there instantly unite to generatecarbonio-acid gas and place the solution under heavy pressure, whereby apowerful stream will be forced out of the nozzle K against the deiectorL, so that the same will be sprayed to cover a large area.

Thus it will be seen thatlhave invented a IOO is automatic inoperation,and which can be placed in any desired locality without piping, andwhich will throw a chemicalized stream onto the fire.

A {ire-pail thus organized constitutes one of the most eiicientautomatic hre-extinguishers with which I am acquainted.

The details of construction herein shown and described may be greatlyvaried by a skilled mechanic without departing from the broad scope oflmy invention as expressed in the claims.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

l. As an article of manufacture, a ire-pail comprising a pail orreceptacle, a horizontal partition dividing the pail into chemical andmixing compartments, a nozzle leading from the mixing-compartment, avalve-seat formed in said partition7 and a glass ball engaging saidvalve-seat and forming a valve to separate said compartments,substantially as described.

2. A fire-pail divided by partitions into two chemical-chambers belowone partition, and a mixing-chamber above said partition, passagesthrough said partition connecting each chemical-chamber with themixing-chamber, valves as glass balls controlling said passages, and asuitable nozzle leading from the mixing-chamber, the whole so arrangedthat two chemicals may be placed in the compartments, and be ordinarilyheld from uniting, but so that if the pail is inverted, the chemicalswill unite in the mixing-chambers, and throw a chemicalized liquid fromthe nozzle, substantially as described.

A fire-pail divided by suitable partitions into two compartments, and amixing-chamber above said compartments, holes through one partitionconnecting said compartments with the mixing chamber, valves as glassballs iitted to said holes, guides adapted to guide said glass ballsinto proper position, and a suitable nozzle leading from themixingchamber, substantially as described.

4. As an article of manufacture, an automatic chemical nre-pailcomprising a receptacle or pail,horizontal and vertical partitionsdividing the receptacle into three departments, two chemical-chambersbeing located below the horizontal partition, and a mixingchamber beinglocated above the horizontal partition, a nozzle leading from vthemixingnozzle as K arranged in said cap, a deflector as L also connectedto said cap,abail arranged to suspend the pail below its center ofgravity, and a fusible connection between the deiector L and the bail,whereby the pail will be held with its center of gravity normally aboveits line of suspension, substantially as described.

6. The automatic {ire-pail consisting of a suitable receptacle dividedby partitions into compartments containing chemicals that are adapted tounite to generate a gas, a suitable cap as H screwed into the top of thepail, a nozzle as K arranged in said cap, a deflector as L alsoconnected to said cap, means for suspending the pail below its center ofgravity and a fusible connection adapted to normally hold the pail withits center of gravity above the point of suspension, substantially asdescribed.

7. An automatic fire-pail consisting of a suitable receptacle or paildivided by a horizontal and by a vertical partition into three chambers,two chambers adapted to receive chemicals below the horizontalpartition, and a mixing-chamber above the horizontal partition, passagesconnecting each chemicalchamber with the mixing-chamber, valves as theglass balls G G normally closing these passages, means for suspendingthe pail below its center of gravity, and a fusible connection adaptedto support the pail in this position, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
